The second full day of the 2012 Summer Olympics started off slow but picked up speed with dramatic turns in gymnastics and a world-record effort in swimming.
The pros for some athletes meant cons for others, however. Saturday's heroes became Sunday's goats. (Yes, we're talking about Ryan Lochte.)
Here are 10 winners and losers from Day 2 in London.
Aly Raisman shocked the world today when she executed a near flawless performance in the preliminary sessions of women's gymnastics.
All the talk has been about her teammates Jordyn Wieber and Gabby Douglas going 1-2 for the individual all-around, with Raisman virtually a non-factor. Some people didn't even think Raisman should compete in the all-around.
Raisman, the oldest member of the five-person squad (18), has always been a consistent worker but was not considered as strong as Douglas and Wieber.
She was a top contender for a slot throughout the Day 2 competition though, while Douglas and Wieber had what they can consider off-days.
Raisman's score of 15.325 on floor gave her a total of 60.391, slipping her past Douglas for the top performance (American and world) and taking her best friend Wieber out of the running.
"Aly’s success today just proves that hard work pays off," U.S. coach Martha Karolyi said in an interview with the Associated Press. "She’s one of the most serious and hardest-working girls in training. So finally it came true, and she was able to perform at the (highest) level."
Raisman finished the day second in the all-around standings.
With Aly Raisman's success came Jordyn Wieber's demise.
Wieber, the defending world all-around champion and favorite to maintain that title after London, was left out of the all-around finals.
Raisman and Douglas simply outperformed her and there is a rule that only two gymnasts per country can advance.
It doesn't matter that Wieber finished fourth out of the entire field. Rules are rules and these rules left Wieber sobbing while she was forced to put on a smile and support her teammates.
Wieber didn't have any major mistakes, but was not her usual consistent self. She had a form break on the uneven bars, some wobbles on balance beam, and stepped out of bounds on floor exercise.
These small mistakes keep her from even having a chance at the all-around title.
The duo only won the U.S. Olympic Diving Trials by .42 points.
They were not at all expected to medal. Bryant and Johnston averaged no less than 7.8 points per dive and hit at least eight on their other four attempts. They did not receive any deductions from penalties on any dive,
It was the first Olympic medal for the U.S. in diving for since Laura Wilkinson's platform gold in 2000.
Ryan Lochte blew the Americans' lead in the 4x100-meter freestyle relay. He entered the water with a 0.3-second lead but couldn't hold off France's Yannick Agnel in the final lap of the race.
This was a similar storyline to four years ago when Team USA had an astounding comeback to beat France.
Lochte, who was given the anchor slot, swam the slowest leg of the final three Americans.
Wu Minxia and He Zi totaled 346.20 points and won gold in the 3-meter synchronized diving event.
The duo led throughout the five-dive round and won by a 24.3 point spread. The American team of Abby Johnston and Kelci Bryant took second.
Wu has three golds, one silver and one bronze in her Olympic career. She could earn another in the individual springboard event, where she has medalled twice before and will compete against He Zi.
Spain continued its subpar play in men's soccer and was eliminated from medal contention.
It lost 1-0 to Honduras on Sunday while Brazil and Japan booked their places in the quarterfinals with victories.
Spain was hoping to add an Olympic gold to the World Cup and European Championship titles held by the country's full national team.
Instead the country suffered its second straight disappointment after losing to Japan in the opening game.
Kim Rhode won her fifth straight Olympic medal in shooting when she took the gold in skeet Sunday.
She now has medals from Atlanta, Barcelona, Athens, Beijing and London and is the first U.S. athlete to medal in individual events at five Olympics.
Out of 100 possible targets, Rhode hit 99. She set a new Olympic record in the morning’s qualifying round with 74 hits out of 75. She was perfect in the final to tie her own world record.
Rhode is 33 and in a competition that doesn't have much age restrictions, she has plenty of opportunities to break her own record.
Hungary lost its first match in Olympic men's water polo in 12 years. The three-time defending champion lost 14-10 to Serbia.
Serbia is now the gold-medal favorite.
Hungary was just not able to match the loaded Serbian side in front of the sold-out arena.
The Hungarians have a record nine Olympic water polo golds, and Serbia is in search of its first gold medal as an independent nation.
Dana Vollmer took the gold in the 100-meter butterfly in 55.98 seconds, good for the world record.
She beat the record of 56.06, which Sweden’s Sarah Sjostrom set at the 2009 World Aquatics Championships when high-tech suits were still legal.
World records have become something of a rarity in swimming since those suits were outlawed (relatively speaking).
After a phenomenal first day of Olympic action, the Great Britain success was not as great in Day 2.
Britain's Rebecca Adlington staged an epic comeback in the 400-meter freestyle, but it just wasn’t enough. The 2008 Olympic champion placed third to Camille Muffat of France and American Allison Schmitt.
Also, the countries' greatest women's distance runner ever, Paula Radcliffe, was forced to withdraw from the marathon after failing a fitness test on her left foot.
An Olympic medal was all that was missing from the 38-year-old marathon world-record holder's trophy case. Commented Radcliffe on the painful decision to withdraw from the London Games, via Sky Sports:
"My sport is a beautiful sport, it gives so much fun and enjoyment, I believe it helps me to be a better person, and I have been very fortunate to experience some great success and have so many beautiful and happy memories.
"However, the downside is that it can break your heart and spirit many times over when your body is simply unable to match what your heart and brain want it to do.
"Sadly mine is not a career or a hobby where mind over matter can work when your body is hurt, nor where giving less than your best each day can ever work."
